I am sorry for taking your time, but how to be so sure of something? Being sure of something garantee you are correct? I sometimes am sure of things and then it turns out I am wrong and then I feel stupid. I beg, if not take too much of your time, to teach me how to be more sure and correct? I think I will be able to accomplish a lot of things, if I devise a system to be sure of things. Please help me.
